  Synthesis and Anti-Neuroinflammatory Activity of 1,7-diphenyl-1,4-heptadien-3-ones in LPS-Stimulated BV2 Microglia Via Inhibiting NF-κB/MAPK Signaling Pathways

  摘要：

  一系列具有不同取代基（HO-，CH3O-，CH3-，Cl-）的1,7-二苯基-1,4-庚二烯-3-酮被合成并在LPS刺激的BV2小胶质细胞中评估其抗神经炎症作用。药理结果显示，带有甲氧基的目标化合物极大地抑制了LPS诱导的NO释放，并且活性化合物CU-19和CU-21降低了LPS刺激的BV2细胞中NO，TNF-α，IL-6和PGE-2的水平，下调了COX-2和iNOS的表达。机制研究表明，CU-19和CU-21抑制了NF-κB的核转运和MAPKs（ERK，JNK和p38）的磷酸化。大鼠的初步药代动力学研究表明，与姜黄素的药代动力学性质相比，CU-19和CU-21的药代动力学性质显著改善。

  Four linear nonphenolic diarylheptanoids were synthesized and their antibacterial activities were studied. (S)-2-Me-CBS-catalysed reduction of alnustone with BH3.SMe2 gave (R) (-)(4E,6E)-1,7-diphenylhepta-4,6-dien-3-ol, a natural product. Reduction of alnustone with Na in t-BuOH at -15 degrees C under NH3 atm gave ( E)-1,7-diphenylhept-5-en-3-one as a Birch-type reduction product. t-BuOK catalysed condensation of benzalacetone with propionyl chloride gave (4Z,6E)-5-hydroxy-1,7-diphenylhepta-4,6-dien-3-one, a natural product. (1E,4Z,6E)-5-Hydroxy-4-phenethyl-1,7-diphenylhepta-1,4,6-trien-3-one, a curcuminoid, was synthesized starting from pentan-2,4-dione in 3 steps. The synthesized chemical compounds were applied against 2 gram-positive bacteria (Bacillus cereus and Arthrobacter agilis), 4 gram-negative bacteria (Pseudomonas aeruginosa, Xanthomonas campestris, Klebsiella oxytoca, and Helicobacter pylori), and 1 yeast (Candida albicans) by the disc diffusion method. All of the synthesized compound exhibited different degrees of antimicrobial activity at concentrations between 20-100 mu g/disc against the test organisms.

  A series of 1,7-diphenyl-1,4-heptadien-3-ones with various substituents (HO-, CH3O-, CH3-, Cl-) on the phenyl rings were synthesized and evaluated for anti-neuroinflammatory effects in LPS-stimulated BV2 microglia. The pharmacological results showed that the target compounds bearing methoxy groups greatly inhibited LPS-induced NO release, and that the active compounds CU-19 and CU-21 reduced the level of NO, TNF-α, IL-6 and PGE-2, downregulated the expression of COX-2 and iNOS in LPS-stimulated BV2 cells. A study of the mechanism of action revealed that CU-19 and CU-21 inhibited the nuclear translocation of NF-κB and phosphorylation of MAPKs (ERK, JNK, and p38). A preliminary pharmacokinetic study in rats revealed that the pharmacokinetic properties of CU-19 and CU-21 were dramatically ameliorated in comparison with the pharmacokinetic properties of curcumin.
